What is a consequence of less tillage in a conservation tillage system?

In a conservation tillage system, one of the primary consequences of reduced tillage is the potential for higher populations of pests, including slugs. This occurs because less tillage means that the soil remains covered with crop residues, which can provide a favorable habitat and food source for slugs and other pests. Additionally, without regular turning of the soil, the pest population may not be disturbed, allowing them to thrive.

While reduced tillage can lead to benefits such as improved soil structure and moisture retention, it can also create microhabitats that support pests more effectively than conventional tillage methods, where more soil disturbance would naturally reduce their populations. Understanding this balance is important for managing crops sustainably in conservation tillage systems.
